1. Operating Instruction
1.1 About this manual
This service manual should be used by specialized engineers authorized by Gyrozen
Co., Ltd.
Any repairing work operated by non-authorized personnel cannot be protected and
guaranteed.
This service manual aims to find possible errors quickly and fix them properly.
Refer to the user’s manual for detailed operation of Centrifuge.
Do not copy or reprint without approval
1.2 Safety label and safety precautions
1.2.1 Safety Label
The labels attached to the device give information for safety.

Attention label to show
risk and warning
Attention label to warn
electric shock
1.2.2 Safety Precautions
•Supply proper voltage power according to device’s power requirement.
•Let all repairing works done by authorized or qualified personnel.
•Use rotors or accessories which are approved by Gyrozen.
•Not try to open the lid and or move the device while the rotor is running.
•Operate the centrifuge with a rotor properly attached and secured to the shaft.
•Not use flammable, hazardous, explosive, or corrosive materials.
NOTE: When it is required to use toxic, radioactive materials or pathogenic micro-
organisms, which belong to the Risk Group II of WHO: “Laboratory Bio-safety Manual,”
should follow the regulation guidelines from WHO.
http://www.who.int/csr/resources/publications/biosafety/Labbiosafety.pdf)
•Keep away hazardous materials farther than 30 cm (12 in) from the device during
centrifugation, as recommended in IEC standards 61010-2-020.
•Keep the rpm or rcf under its maximum speed in the case that the density of sample
materials is greater than 1.2 g/ml to avoid rotor failure.
•Load samples symmetrically in the rotor diagonally to make balance between the tubes.
•Balance the load on the rotor totally to prevent the damage to the device even by using
several water-filled tubes.

•Place device on a flat, level, rigid and stable surface.
•Disconnect power supply prior to maintenance and service work to avoid electrical shock.
•Use proper disinfection procedures when centrifuging bio hazardous compounds.
When a blackout takes place while the device is running, the door does not open. And the
rotor speed begins to decrease at natural level. Even if the power turns on before the rotor
stops completely, the rotor does not return to the original speed, but decreases more rapidly
with buzzer sound.
The door is closed/opened automatically by a door lock unit operated by a motor, and it
will not be opened while the rotor is running at all. Even if the door is opened accidentally,
a door limit switch senses it instantly to make the rotor speed decrease.
If the rotor loses balance while running by any reason, it invokes vibration on the device
itself. In this case the Imbalance sensor senses it and makes the rotor begin to decrease with
preset level issuing Imbalance Error warning. This safety function protects the device from
damage during operation.

2. Installation
2.1 Positioning
On the declined place the weight of rotor can make the shaft warp in the long time running.
Smooth air circulation is needed to increase the cooling effect. So the space between the
device and wall should be larger than 12 inch(30cm). And dust should be kept away for it
can prevent air from flowing smoothly.
In the condition that temperature is too high, the cooling function cannot work effectively.
And in that too low, the electric parts can work unusually. And it that humidity is too high,
rotor can rust and electric part can get dew which invokes disorder.
Rotor and shaft can be corroded by some kind of gas such as Chlorine gas or sulfurous
acid gas. So this kind of gas should be kept out.
2.2 Leveling
The target place should be confirmed to be leveled by leveling bar.
2.3 Installation procedure
1) Unpacking
•Untie the plastic banding over the paper box and get lid of box from the device
main body
•Unwrap the vinyl coat surrounding the main body and remove stuffing cushion from
chamber
•Place the device on a proper place by moving device’s wheel
2) Delivery Check
•Rotor(Optional)
•Rotor lid open/close tool(with an order of large capacity & Fixed Angle rotors)

3) Electricity Check
2236R model needs 110V or 220V voltage. Connect the device to adequate power
outlet.
Requires 4K VA for optimal operation. Therefore, should secure sufficient power
inflow in single phase current. With the supplied power cord and plug and a wall
socket, fix the wall socket on proper place and make enough place for the device
installation

If the voltage power input is more than +/- 10% of the recommended voltage or
fluctuating frequently, it may affect some functions of the device. In that case it is
recommend to use AVR(Automatic Voltage Regulator)
If you want to use the device under the other voltage range, please contact us for
safe usage
4) Removal of Safety Padding
2236R is delivered with its chamber filled with safety padding. As the 2236R has the
rotor auto-recognition function, the system unnecessarily tries to identify a rotor if
you turn on the power before fixing a rotor. In this case an error signal is issued
because of absence of the rotor. When this error appears, press ‘OK’ button at the
window and then press ‘DOOR’ button to open the door. Mount/re-mount the rotor
and press ‘START’ button to recognize the rotor again.
5) Power On/Off and Door Release
The power is provided via earth leakage breaker switch which is attached on the
right side of the device. Connect the power cord properly and turn on the earth
leakage breaker and the power is on, the latest setting value recalled with
beeping sound.
Press the ‘Door’ button on the control screen to open the door
Auto-Door Lock
The door should be closed only by gentle press-down motion

6) Emergency Door Open
In some cases, especially for emergency, it is needed to open the door manually. In
this case, you can use the emergency door open hole at the front side of the device.
At first stop the device and then insert the T-wrench into
the door open hole and then Turn to left the T-wrench.
7) Balance Adjustment
The imbalance of the machine causes not only momentary troubles of vibration,
noise and error during operation but also ultimate damage on the device. The
following steps are recommended to check the balance status of a rotor with a
balancing level tool included.
Mount the rotor and place the balancing
level crisscross pattern on the rotor.
Confirm that air bubble of
window of the balancing level is
within the black lines.
To adjust the balance status, rotate the red
colored ring at the wheel caster clockwise or
counterclockwise until the device is well
balanced.

8) Rotor assembling and disassembling
To assemble a rotor, mount the proper rotor onto the motor shaft.
Grasp the rotor with one hand, and put the rotor locking tool into the central
groove of the rotor. Finally rotate the tool clockwise until tightly assembled.
To disassemble the rotor, rotate the rotor locking tool counterclockwise.
To open or close the rotor lid, grasp the rotor with one hand and rotate the rotor
lid nut counterclockwise for opening, and clockwise for closing with the other
hand.
